GeForce GT 240 GDDR5 1GB vs GeForce GTX 650 Ti 2GB

Intro

The GeForce GT 240 GDDR5 1GB makes use of a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 memory runs at a frequency of 850 MHz on this specific model. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the GeForce GTX 650 Ti 2GB, which features core clock speeds of 928 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 memory. It features 768 SPUs along with 64 TAUs and 16 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
